The fuss over the failure of the auto manufacturers to comply with the diesel standards for nitrous oxides is remarkably telling. First of all, it should be made completely clear that building automobiles remains arguably the most difficult undertaking the Producer classes ever make. Car manufacture is more difficult than aerospace because of the sheer volume of units produced. Building an airliner is much more akin to building a skyscraper because very few are made so many operations are allowed to be relatively inefficient. Cars are much more difficult to make than medical devices because of the incredible cost constraints. And of course, cars are more difficult to make than computers because cars also have computers plus everything else.

The reason the complexity of automobile manufacture is so important to remember is that these facts make a mockery of what the technologically illiterate believe about cars. For example, there are those who think that some day, a lone inventor in a garage will make some stunning breakthrough in emissions control or fuel efficiency. Obviously, that will never happen but the true believers will explain that is because the big boys hate honest competition and will crush the lone genius. And now we see the environmental extremists thinking that the only reason companies are failing to comply with emissions standards is because they are greedy or are unwilling to put forth the necessary efforts.

However, when everyone seems to be failing to meet the new diesel standards, the question must be asked, "Are the standards reasonable?" My guess is that they are not. But the environmental bureaucrats will never admit they are wrong. Because they refuse to admit that there are physical realities that are responsible for this outbreak of environmental lawlessness, the possibilities for real progress are likely to degenerate into expensive and pointless lawsuits. Environmentalists are fond of pointing out that the laws of nature will ultimately trump all other considerations, yet they will not realize that they cannot regulate emissions problems out of existence by issuing mandates that are physically impossible to accomplish.

Unfortunately, there are many people who seem to believe that the problems of climate change can be solved if only we elect politicians who will enact tougher legislation to outlaw greenhouse gasses. Such people are worse than wrong, they have delayed the possibilities for progress for at least three decades now.

Four more carmakers join diesel emissions row

Mercedes-Benz, Honda, Mazda and Mitsubishi’s cars are shown to emit significantly more NOx pollution on the road than in regulatory tests

Damian Carrington, 9 October 2015

Mercedes-Benz, Honda, Mazda and Mitsubishi have joined the growing list of manufacturers whose diesel cars are known to emit significantly more pollution on the road than in regulatory tests, according to data obtained by the Guardian.

In more realistic on-road tests, some Honda models emitted six times the regulatory limit of NOx pollution while some unnamed 4x4 models had 20 times the NOx limit coming out of their exhaust pipes.

“The issue is a systemic one” across the industry, said Nick Molden, whose company Emissions Analytics tested the cars. The Guardian revealed last week that diesel cars from Renault, Nissan, Hyundai, Citroen, Fiat, Volvo and Jeep all pumped out significantly more NOx in more realistic driving conditions. NOx pollution is at illegal levels in many parts of the UK and is believed to have caused many thousands of premature deaths and billions of pounds in health costs.

All the diesel cars passed the EU’s official lab-based regulatory test (called NEDC), but the test has failed to cut air pollution as governments intended because carmakers designed vehicles that perform better in the lab than on the road. There is no evidence of illegal activity, such as the “defeat devices” used by Volkswagen.

The new data is from Emissions Analytics’ on-the-road testing programme, which is carefully controlled and closely matches the real-world test the European commission wants to introduce. The company tested both Euro 6 models, the newest and strictest standard, and earlier Euro 5 models. Data showed that:

Mercedes-Benz’s diesel cars produced an average of 0.406g/km of NOx on the road, at least 2.2 times more than the official Euro 5 level and five times higher than the Euro 6 level. A spokesman for Mercedes-Benz said: “Since real-world driving conditions do not generally reflect those in the laboratory, the consumption figures may differ from the standardised figures.”

Honda’s diesel cars emitted 0.484g/km of NOx on average, between 2.6 and six times the official levels. A spokesman for Honda said: “Honda tests vehicles in accordance with European legislation.”

Mazda’s diesel cars had average NOx emissions of 0.293g/km in the real world, between 1.6 and 3.6 times the NEDC test levels. One Euro 6 model, the Mazda 6 2.2L 5DR, produced three times the official NOx emissions. A spokesman for Mazda said: “In compliance with the law, Mazda works hard to ensure that every petrol and diesel engine it makes fully complies with the regulations.”

Mitsubishi diesel cars produced an average of 0.274g/km of NOx, between 1.5 and 3.4 higher than in the lab. “The NEDC was never intended to represent real-world driving,” said a spokesman for Mitsubishi.

The Emissions Analytics data seen by the Guardian also found Citroen, VW and Audi NOx emissions to be higher on the road than in the EU lab test.

“The VW issue in the US was purely the trigger which threw light on a slightly different problem in the EU - widespread legal over-emissions,” Molden said. “For NOx, [diesel] cars are on average four times over the legal limit, because of the lenient nature of the test cycle in the EU.” The Emissions Analytics tests showed 4x4s to have the highest NOx emissions, with several unnamed models emitting 15 times official levels and one more than 20 times.

“MEPs have been fighting for years to reform EU rules on diesel emissions-testing so they reflect real-world emissions. Yet the powerful car lobby and national governments have fiercely resisted these life-saving changes,” said Catherine Bearder, a LibDem MEP and a lead negotiator in the European parliament on the EU’s new air quality law. “The people of Europe have waited long enough for cleaner air, they must not be made to wait any longer.”

Friends of the Earth air pollution campaigner Jenny Bates said: “With further manufacturers implicated, this is yet more evidence that this scandal goes way beyond VW, and should cause decisionmakers to question the very future of diesel vehicles on our roads. This is a massive public health disgrace and the failure to prevent vehicles breaking pollution rules will have cost lives.”

Two car companies, Mercedes and Honda, said that they supported a tightening of the regulations. “Mercedes-Benz emphatically supports the introduction of the WLTP test [which] is designed to supersede the NEDC, with the goal of bringing standardised and real-world consumption closer together,” said the spokesman. “To this end, we actively support the dialogue between industry (through trade group ACEA [European Automobile Manufacturers Association]) and the authorities.” Honda said it supported “additional testing in order to help strengthen regulatory and consumer confidence”.

However, in a letter seen by Reuters to EU officials, the ACEA chairman and Renault chief executive, Carlos Ghosn, said that no significant progress on NOx was possible before 2019. Reuters said that ACEA, which lobbies for Europe’s carmakers in Brussels, told the officials on 1 October that the NOx limit for a new, more realistic test should be 70% higher than today’s limit. An ACEA spokeswoman said it was “too early in the process to confirm or comment on hypothetical figures.”

“These new test results [from Emissions Analytics] prove that the Volkswagen scandal is just the tip of the iceberg. What we are seeing here is a dieselgate that covers many brands and many different car models,” said Greg Archer, an emissions expert at Transport & Environment. “The only solution is a strict new test that takes place on the road and verified by an authority not paid by the car industry.” more
